This research of the knowledge inside the 2004 IUCN crimson checklist of Threatened Species offers an perception into the prestige and tendencies of the world’s species of crops and animals, with a spotlight on these at maximum danger of extinction. The book highlights the taxonomic teams and species which are on the maximum threat of extinction; contemporary documented extinctions; tendencies within the prestige of threatened species, together with the recent pink record Index; areas of the area the place threatened species are usually chanced on; the threats which are using species in the direction of extinction; the social and monetary context during which extinctions are occurring; and the conservation responses which are to be had. This intensive research is the 1st significant e-book by way of the purple checklist Consortium, a gaggle of enterprises comprising IUCN (in specific the Species Survival Commission), BirdLife foreign, Conservation overseas (in specific the heart for utilized Biodiversity Science), and NatureServe.

1. , those groups completely or almost completely evaluated), the figures in the last column are gross over-estimates of the percentage threatened due to biases in the assessment process towards assessing species that are thought to be threatened, species for which data are readily available, and under-reporting of Least Concern species. The true value for the percentage threatened, lies somewhere in the range indicated by the two right-hand columns. In most cases this represents a very broad range.
Where information is available, species have undergone rapid declines in abundance. Severely threatened species include the Australian endemic species, Harrisson’s Dogfish Centrophorus harrissoni and the Southern Dogfish C. uyato with declines of >99% in two decades due to commercial fishing (Cavanagh et al. 2003; Graham et al. 2001). Deep-sea data collection is challenging, and the SSG is encouraging the precautionary approach to management as a matter of urgency. 19 Damba Mipentina Paretroplus maculatus (Critically Endangered) endemic to Madagascar, has undergone severe declines due to severe fishing pressure, impact of introduced inavsive species, and habitat destruction.
This approach can also be scaled down to the river basin level, providing biodiversity information to guide both the site selection of water development projects, and the minimization or mitigation of any subsequent impacts. The assessment also provides an essential baseline for long-term monitoring purposes. An additional benefit of the regional approach is increased regional capacity for biodiversity assessment through training in assessment tools such as for the Red List, and through direct involvement of regional scientists in the assessment process.
